The 14th Amendment, ratified in 1868, states that all persons born or naturalized in the United States are citizens. This doctrine has been law for over 150 years, creating an automatic pathway to citizenship for virtually everyone born on U.S. soil, regardless of their parents' immigration status.
This means a child born in the U.S. to undocumented immigrants is a citizen from birth, automatically able to sponsor family members and participate fully in U.S. politics. An estimated 4 million people born in the U.S. since 2000 to at least one undocumented parent are now U.S. citizens under this rule.
The 14th Amendment's language is unambiguous: "all persons born... in the United States, and subject to the jurisdiction thereof, are citizens." Some constitutional scholars and politicians argue "subject to the jurisdiction thereof" excludes children of undocumented immigrants, but federal courts have rejected this interpretation for decades. In 2025, an executive order attempted to deny citizenship to babies born to non-citizen parents and signed challenge petitions, but federal judges blocked the order nationwide, finding it violated the 14th Amendment's plain text. Any successful change would require a constitutional amendment—a two-thirds majority in both houses of Congress plus three-fourths of all states.
Birthright citizenship determines whether 4 million Americans born since 2000 have full legal standing as citizens or face legal limbo. It's also one of the most actively contested constitutional doctrines: attempts to limit it through executive action have already reached federal court, and the question could reshape immigration law and political power.
People think birthright citizenship is a policy Congress created. It's actually a constitutional rule baked into the 14th Amendment. Congress cannot override it without a constitutional amendment, which requires nearly impossible supermajorities—two-thirds of both chambers plus ratification by three-fourths of the states.
